You can filter what individual routes are sent (out) or received (in) to any interface within your EIGRP configuration.
One example is noted above. If you filter outbound, the next neighbor(s) will not know about anything except the 172.16.0.0/16 route and therefore won’t send it to anyone else downstream. If you filter inbound, YOU won’t know about the route and therefore won’t send it to anyone else downstream.
